Problems solved by technology

Since the motion sensor readings can change rapidly, maintaining synchronization between the raw motion sensor readings and the advertised motion sensor readings will result in high communication overhead between the M2M device and the M2M server, which may be due to the limited Bandwidth becomes even unaffordable

Embodiment Construction

[0062] Figure 6 A smart traffic scenario where users subscribe to road condition data is shown. In this scenario, toll company A deploys roadside cameras that can report road conditions to an M2M server residing in the cloud and operated by M2M service provider B. While it is possible to receive traffic condition information from passing vehicles, it is not the focus of this use case. M2M service provider B deploys M2M server 602 (ie, IN-CSE) to provide near real-time road conditions to M2M users C, D and E (eg, IN-AE installed on commuters' smartphones). In this use case, roadside cameras are assumed to have M2M service layer capabilities (eg data repository and management) as M2M devices. Due to the large number of video files generated by roadside cameras, only conditions or events of interest (e.g., light traffic congestion, moderate traffic congestion, and severe traffic congestion) will be reported to the M2M server 602 and ultimately based on subscription / notificatio...

Abstract

The subscription analysis and clustering mechanism can cluster similar subscription requests from different subscribers and generate aggregated notifications for them. The subscription analysis and clustering mechanism reduces the number of subscription request messages and notification messages, thereby improving subscription efficiency and making the M2M / IoT service layer more efficient and scalable.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 62 / 164,146, filed May 20, 2015, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] From the perspective of the protocol stack, the service layer 102 is generally located above the application protocol layer 104 and provides value-added services to the application 106 . As such, the service layer 102 is generally categorized as a "middleware" service. For example, figure 1 An exemplary service layer 102 between an IP network stack and applications 106 is shown. [0004] The M2M service layer 102 is an example of a type of service layer dedicated to providing value-added services for M2M type devices and applications. More recently, several industry standards bodies (e.g. oneM2M described in oneM2M-TS-0001, oneM2M Functional Architecture-V-1.6.1) have been developing M2M service lay...
